FLOOR CONNECTION FOR CLOSETS.

l Specification of Letters Patent.

Patented J an. 13, 1914.-.

To all rwhom t may concern.

Be it known that I, HARRY J. MGNAMARA, of Brooklyn, New York, have invented cert-ain Improvements in Floor Connectionsfor Closets, of which the following description, in connection with the accompanying drawings, is a specification, like'numerals on the drawings designating like parts.

This invention relates to plumbing fixtures, and isvof special utilityl when embodied in a water-closet of the screwdown type, although I contemplate the utilization of my improvements in any field for which they are adapted by their nature.

An important object of my invention 1s to provide a closetwith means of attachment by which the solidity and other advantages of the screw-down type can be secured without requiring the complete rotation of the earthenware, for the bulk, and particularly the length, of the earthenware has frequently prevented the use of the eX- isting forms of screw-down attachments in' confined situations where space was lacking for the necessary rotation of the earthenware around the vertical aXi's of its joint with the bend of the soil-pipe. Accordingly, in carrying my invention into effect, prefer to provide an attachment including a connecting member, rotatable independently of both the ea-rthenware and the bend, or as an alternative I may provide an attachment with which a limited degree of rotation of the earthenware will suflice to effect a true screw-down connection uniting the. closet solidly to that portion off-the'soil-plpe selccted for the point of attachment, whether usual bend or another soil-pipe mit some lateral adjustmentl between the earthenware and connecting member without danger of a leak.

Still another object of my inventionis to reduce the number of movable Vparts in the joint and to simplify their construction, reducing to anegligible quantity theV opportunity for maladjustments, displacement of adjustments and failure of individual parts by breakage, and also to improve the char-v acter and situation of the packing, elimina-ting the necessity for putty-.paraffin and other'plastic materials, and also of lead and solder.

I prefer to'accomplish the above objects by extending the horn of earthenware already mentioned so that it enters the bend, and to interpose` the packing between the horn and bend, under compression between a horn flange and the connecting member, so that the packing is set in an operation unitary with the screwing down ofV the closet, and when set is not in position to be subjected to residual Huid containing corrosive uric acid, since the flushing fluid will all drip back into the bend, and not lie on the packing, except in the event of a leaky packing, which will permit the flushing fluid to pass up and escape over the mouth of the bend and outfrom beneath the base pf lghe earthenware, giving notice of the Still other objects of my invention comprise the provision of a connection which can be used equally well with iron or lead bends, can be adjusted quickly, is free from parts o-f brass and other expensive material, insures an even pressure all around the joint, and permits the hub ofthe bend or other soil-pipe member to be brought flush with the floor, economizing space. v

The various features of my invention will be illustrated and described fully inthe accompanying drawings and specification and pointed out in the claims.

In the drawings, Figure `1 is a View in vertical sectionof the connecting portions of a Awater-closet installation in the construction .of which my improvements vhave been embodied.V Fig. 2 is a plan view, looking upwardly, of the base [of the closet, taken separately from the soil-pipe,but showing the connecting member in place; and Figs. 3 and 4 show, separately,in side elevation and plan, respectively, the connecting member.

In the embodiment of my invention selected Vfor illustration and description to enable ready and complete understanding of my improvements, the parts designated by the reference numerals 1, 2 and 3 respectively are the base of a water-closet, the upright Y of a soil-pipe, and a bend intervening between the vertical riser of the soilpipe and the closet, and with which the closet is to be connected in the instance se- 'Y lected for illustration by way of example.

The parts above described may be of any suitable construction and material, and may conveniently comprise an iron soil-pipe, an iron or lead bend, and an earthenware closet, as is common in such installations;

As one convenient form of construction I have shown themouth 4 of the bend 3 as brought up substantially flush with the surface 5 of the floor G, which may be of tiles, cement or any other material usual or suit-- able for floor surfaces, my improvements being applicable with notable ease to installations upon tile flooring, owing to the absence of parts, such as bolts, requiring special holes in the floor surface, since my improved connection is preferably accomplished directly between the ycloset 1 and the soil-pipe member 3 selected, as will now be described. This connect-ion may be accomplished by any suitable means, and as one convenient form of connection, I have shown the closet 1 as having a part S, preferably constituting an integral horn or extension of the earthenware part of the closet, projecting downward into the mouth 4 of the bend 3, so that the effluent from the closet is delivered directly from the earthenware 8 to the metallic bend 3 without passing any cracks or crevices within which particles of organic matter may nd lodgment and there decompose. This horn will pref-` erably be provided with an exterior flange 10 which may conveniently be situated around its bottom, this flange serving as an abutment to coperate with a connecting member 12 which I prefer to provide, in accordance with an Vespecially important object of my invention, for the purpose of avoiding the complete rotation of the closet 1, such rot-ation being impossible when, as

coperate with the flange 10, I have shown the connector 12 as split vertically, as at 20, and for the purpose of providing means for its rotation to effect the screwing-down movement, I have shown flanges 22 on the parts 12, these flanges preferably being of suitable construction for engagement by a spanner or other tool to rotate the connector about its vertical axis. For this purpose, I have shown the flanges `as having a series of holes 24, and as these apertured flanges will preferably lie beneath the earthenware base 1 of the closet, for their concealment and protection, I prefer to provide the base 1 with suitable means of access to the connector 12, as for example the slots 26, through which t-he spanner or other tool may pass to the holes 24, and these slots may be closed,

` ordinarily, as by stoppers 28.

At 30 I have shown a packing, which may be of any suitable material, such as lampwick and graphite, and if desired, I may provide a wear-ring or washer 31, to protect the packing 30 when the connector 12 is forced against it, rotatively.

vI prefer to arrange for the rotation of the segment-al parts of the member 12 in assembled relation as a unitary structure independently of both the closet 1 and bend 3, so asto permit a true screw-down relative movement of the connector and closet co-axially with respect to the bend, and as a convenient expedient to this end I have threaded the periphery of the connector 12 and provided a correspondingly threaded annular retaining member or collar 16 to surround the parts 12 and coperatie wit-h them to hold in place the packing ring 30, the whole being screwed down against the flange 10 within the mouth 4 of bend 3, the lat-ter being provided preferably with a threaded seat 18, which seat may be integral with the material of the bend, or may, as illustrated, comprise a spud, bushing or nipple -18 of cast iron, secured suitably 1witlliin the mouth 4, as by a calking 19 of eac.

The above arrangement is Vof particular utility where the bend 3 is of lead, sinceV it permits the provision of a durable sea-t 18 within which the connector parts 12 and 16 can be screwed in and out for adjustment and removal without damage to the bend when the latter is of lead.

In operation of my improved device, after installation of the plumbing parts to which the attachment is to be effected, as for example, the soil-pipe members 2 and 3, rela# tively to the floor 6, the nipple, spud or seatmember 18 is emplaced, if such a separately formed seat is required for the protection of the mouth 4 of the bend 3, being preferably calked as at 19, and the halves 12 of the split connector are assembled upon theneck of the horn 8, above the flange 10, with the packing 30 lying upon the flange, the collar 16 is screwed home surrounding the parts 1.2 and packing 30, and the closet is lowered until the horn 8 passes into the mouth 4, and the threaded periphery of the collar 16 can be .engaged with its threaded seat in spud 18. A spanner or other tool may then be inserted, through the slots 26 of the base 1,

` into the holes 24 .1n flanges 22 of connector 12, and the connector screwed home, its action upon flange 10 through ring 31 and packing serving to draw the rim of the earthenware base l rmly down into engagement at all points with the surface 5 of floor 6, the packing 30 insuring a fluid-tight and gas-tight joint between the horn 8, collar 16 and connector 12, while the usual lead calking 19 between spud 18 and bendmouth 4 insures a similarly tight joint at that region. f

By a reversal of theH above operation, the kcloset may be removed, at any time, without impairing the integrity of the attaching means, inasmuch as no putty orjother plastic material need be employed, nor any lead, between the movable connecting parts, with the exception, ii desired, of the usual white lead between surfaces having a relative movement.

the claims read in connection with this speciication.

What I claim as new and desire to secure by Lettersk Patent is 1. The combination with a water-closet having a base to be engagedwith a door, of a tubular connecting device mounted rotatably upon said base and presented in position for rotatable telescopic engagement within a soil-pipe member, having means acting, upon said rotation of said connecting device, when assembled with said closet and soil-pipe member, to draw said closet into contact with said loor regardlessof the relative axial positions of said base and soilpipe member, and of the position of said soil-pipe member relatively to the floor.

2. The combination with an interiorly threaded soil-pipe member, of an earthenware water-closet having an integral Iianged horn to enter said member and a metallic connector split for assemblage in annular relation upon the neck of and a retaining collar threaded interiorly to receive said horn and threaded peripherally, connector parts and -to screw down as a unitary structure therewith between said horn andmember, into engagement with said flange to cause telescopic movement of said horn and soil-pipe without relative rotation thereof.

Signed at Brooklyn, in the county of Kings and State of New York, this 24th day of August 1911.
